Mathematical and Numerical Methods for Analysis & Design of Electromagnetic Fields

Abstract

Report covers 4 specific areas: 1) Wave Propagation and Scattering which encompasses the essentials of direct scattering codes, new integral equation formulations, preconditioning, a posteriori error estimation, boundary and finite elements, finite difference methods, and parallelization; 2) Inverse Scattering and Imaging in which the forward codes play an essential role but where the emphasis is on target identification and non-destructive microwave imaging of structures including biological (dispersive) objects; 3) Comp1ex Media and Approximating Boundary Conditions, which include various impedance, reactive and conductive conditions, which better, model the effects of dielectric, anisotropic or dispersive material or layers of such material with possible rough boundaries; and 4) Antenna Design which not only includes calculation of radiation patterns from complex structures, including mutual coupling and near field interactions, but also the development and application of optimization methods for realistic design problems.
